I rolled back to 3.2.2 from 3.2.4, and it started working again on the eGPU. Both 3.2.3 and 3.2.4 kept failing with “out of memory” errors. Obviously, the internal still does not work.
Our dev team is suggesting that you may have increased stability in the app by running one filter at at time and then re-importing the resulting file to run the next filter.
We are working on adding this ability in the app, but for now this method should work on your system.
